`1 Claim. 1

This invention relatesto inotcr vehicle wheels of the deniountable rim type, and yin particular a rimzhaving a separable Aflange on vone sideand with U-shaped locking elements extended inwardly from the flange and positioned to slide overe'spaced `inwardly extended lugs onthe edge of the rim for `looking the flange `to `the rim at spaced points extended continuously around the run.

4The purpose of this invention is to provide means for securelylocking a separable flange on a demountable rizn whereby the flange is secured to the rim at a plurality of spaced points and wherein the iiange is secured in position with locking dogs.

Various devices have been provided for mounting separable flanges on dei-mountable rims of motor vehicle wheels, however, where the flanges and rims are provided with interlocking elements it is diliicult to positively secure the parts assembled without bolts, or other mechanical locking elements. With this thought in mind this invention contemplates a separable iiange having spaced U-shaped sections depending from the inner edge thereof, with the sections positioned to slide over inwardly extended lugs on the ad" joining edge of the rim and with spring actuated locking elements mounted on the separable flange and positioned to snap over stops on the lugs of the rim for positively locking the ange on the run.

The object of this invention is, therefore, to provide means for combining spring actuated locking dogs with spaced locking elements of iianges of demountable rims whereby the flanges are positively secured to the rims.

Another object of the invention is to provide means for securing separable iianges of demountable rims to the rims without screws, bolts, or other mechanical locking elements.

A further object of the invention is to provide an improved demountable motor vehicle rim having a separable flange secured, at a plurality of points, to the rim, in which the rim is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a rim for a motor vehicle wheel having an integral iiange on one side with a separable fiange on the opposite side and with U-shaped locking elements positioned in spaced relation and extended inwardly from the flange and wherein said U-shaped locking elements are adapted to slide over lugs extended inwardly from the rim whereby with the parts secured in assembled relation with spring actuated dogs the separable ange is locked to the rim.

Other features and advantagesof 4'the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a side elevational View showing the rim `and `web of a motor vehicle wheelwith parts of the tire broken away.

Figure 2 is a detail showing part of the wheel rim shown in Fig. l illustrating the separable flange in the locked position on therim.

`Figure 3 is a detail similar to that shown in Fig. 2 showing the iiange with the rim omitted.

Figure 4 is a detail also similar to that shown in Fig. 2 showing the rim with the flange omitted.

Figure 5 is a typical cross section taken on line 5 5 or Fig. 1 showing the rim or the wheel with the parts assembled, and with parts of the tire and rim broken away.

Figure 6 is a detail showing one of the U shaped locking sections of the ange with the spring actuated dog extended across the locking section for preventing a lug of the rim of a wheel sliding out of the section.

Figure 7 is a detail showing a section of the riin and illustrating a flange providing a stop at the ends of the lugs extended inwardly from the edge of the rim.

Figure 8 is a detail showing the rim and flange assembled with the dog positioned against the stop.

Figure 9 is a detail showing a longitudinal section through a portion of the rim showing the locking dog in the position of securing a lug of the rim in the U-shaped locking elements of the iiange.

Figure 10 is a section similar to that shown in Fig. 9 showing the locking dog moved outwardly to release the lug of the rirn of the wheel and showing the lug extended from the slot of the locking element of the ange.

Figure l1 is an exploded view similar to the view shown in Figs. 9 and 10 showing the ange separated from the rim.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved demountable rim of this invention includes a rim I0, an integral. flange |00, a removable iiange II, spaced lugs I2 extended inwardly from the rim, meshing U-shaped elements having outer walls I3, inner walls I4 and connecting sections I5 extended inwardly from the ilange and positioned to receive the lugs I2, locking dogs I5 and Il and stops I8 extended from the ends of the lugs I2.

The inner walls I4 terminate at the point I9 whereby the ends of the walls are spaced from the ends of the sections I5 and outer walls I3 providing a notch for receiving the stops I8 of a lug positioned to extend into the groove 20 of the U-shaped section.

The dogs I6 and I1 are carried on the ends of resilient arms 2i and 22, respectively and the ends of the arms are secured to the outer faces of the walls I3 by welding or other suitable means.

With the parts formed in this manner the flange II is removed by withdrawing the dogs I6 and I 'I to positions, as illustrated in Fig. 10 whereby the flange I I may be rotated in a counterclockwise direction with the Ushaped sections sliding of of the lugs I2 of the rim. With the U-shaped sections positioned between the lugs I2 the iiange is free and may readily be removed from the rim.

In assembling the flange on the rim the U- shaped sections are pressed through the spaces between the lugs I2 with the upper edges of the flange against a tire, as indicated by the numeral 23 and with the Iiange in position, as illustrated in Fig. 5 it is turned in a clockwise direction whereby the lugs I2 enter the slots 2B of the U-shaped members with the dogs I6 and I'l riding over the outer faces of the lugs, as shown in Fig. 10, and as the lugs are nested in the U-shaped sections the dogs drop over the stops I8 at the ends of the lugs, as illustrated in Fig. 9 whereby the lugs are.locked in said 4 U-shaped sections and the flange is securely locked to the rim of the wheel.

It will be understood that modications, Within the scope of the appended claim, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

In a demountable rim for motor Vehicle wheels, the combination which comprises a rim having a flange on one side integral therewith and having spaced lugs extended radially inwardly from the opposite side, said lugs having stops on one of the ends thereof, and a second flange having spaced U-shaped sections extended radially inwardly from the inner edge, said second ange positioned on the side of the rim on which the lugs are positioned and with the said U-shaped sections positioned to pass between and receive the lugs of the rim, and dogs carried by the ends of resilient arms mounted on the second flange and positioned to extend over ends of the lugs for locking the lugs in the U-shaped sections of the flange.
